Structural analysis of photovoltaic modules The basic service life requirement of photovoltaic modules is that "after 25 years of outdoor work, it can still maintain 80% of the maximum output power of the initial value, and it is also required that it can effectively resist the impact of external forces. Photovoltaic modules are mainly composed of solar cells, backplanes, photovoltaic glass, packa...
At present, there are many models of inverters on the market. In order to simplify management and explore the advantages of centralized procurement, many EPC manufacturers often use limited inverter models to do as many field designs as possible, which will inevitably involve the reduction of inverters. Content usage issues. A small reduction in capacity is not a big problem; but a large reduction...
Photovoltaic inverters are composed of circuit boards, fuses, power switch tubes, inductors, relays, capacitors, displays, fans, radiators, structural parts and other components. The service life of each component is different. The service life of the inverter can be explained by the "barrel theory". The maximum capacity of the barrel is determined by the shortest board, and the service life of th...
Inverters running in summer may feel hot to the touch due to their high shell temperature. And why does the casing feel hot? The following will do some analysis and answers for these two problems combined with inverter heat dissipation. The components in the inverter have their rated operating temperature. If the heat dissipation performance of the inverter is poor, as the inverter continues to wo...
The South Korean Ministry of Industry, Trade and Energy (MOTIE) approved a solar panel recycling program at a ministerial meeting held by Prime Minister Han Duk-soo a few days ago. It is reported that the new regulations establish a standardized collection system for each major region of the country to ensure that the recycling/reuse rate of waste solar panels exceeds 80%. At the same time, the pl...
A 7.7-magnitude earthquake hit southeastern Turkey near the Syrian border in the early morning of February 6, local time. The epicenter was located in Gaziantep Province, Turkey. Buildings collapsed on a large scale and tens of thousands of people were killed or injured. As of press time, there are still a series of aftershocks in the local area, and the scope of the earthquake's impact has expand...
Recently, the International Energy Agency (IEA) released a new market report on the outlook of the renewable energy market in 2023 and 2024. Globally, new renewable energy capacity will soar from 107GW to more than 440GW by 2023, the largest increase ever, the report said. In 2023, solar energy will still be the main source of global renewable energy capacity expansion, accounting for 286GW, of wh...
On the evening of July 11, Deye shares issued an announcement saying that recently, the company found that the micro-inverters produced and sold by the company reported by the media were inconsistent with the certification. The article mainly questioned the micro-inverters sold by the company to Germany because of The lack of relays does not meet the German VDE4105 grid-connected certification con...
With the popularization and application of industrial and commercial photovoltaics, more and more industrial enterprises are using their factory roofs to build photovoltaic power generation system. There is usually no objection to installing photovoltaics on the south slope, but how to deal with the installation of photovoltaics on the north slope of the color steel roof. Whether to continue to us...
The ability of a solar power system to meet the electricity demand of monitoring devices depends on several factors, including the power requirements of the devices and the capacity of the solar system. When determining if a solar system can meet the electricity needs of monitoring devices, consider the following: Power Consumption of Monitoring Devices: Review the power specifications of the moni...
The grid-connected energy storage system refers to the power generation and energy storage system that is integrated into the grid, and the generated electricity may be used for its own use, and the surplus is supplied to other users in the grid. The entire system is a power generation system including photovoltaic module arrays, photovoltaic controllers, battery packs, battery management systems ...
